AI Article Synopsis
- A new method for determining radical concentrations using Electron Paramagnetic Resonance (EPR) is introduced, eliminating the need to measure factors like cavity quality and receiver characteristics.
- The method simplifies the measurement process to a few key variables, including geometrical factors, the area under the EPR absorption curve, and specific field strengths.
- High accuracy, around 0.5%, is achievable, and the technique is supported by principles from complex function theory.
Article Abstract
A new method for precise absolute determination of radical concentrations by EPR is described. Cavity quality factors, cavity mismatching, power levels and receiver characteristics do not have to be measured. The measurement of radical concentration is reduced to the determination of geometrical factors, the area under the EPR absorption curve, the LF modulating field strength and a frequency change. Accuracies in the 0.5% range can be reached. The method is checked by and bared on complex function theory.

Nomogram-based Approach for Predicting Complication Risks Following Prepectoral Direct-to-Implant Breast Reconstruction.
Plast Reconstr Surg

Department of Plastic Surgery, Samsung Medical Center, Sungkyunkwan University School of Medicine, 81 Irwon-ro, Gangnam-gu, Seoul, South Korea.
Background: Despite the recent steep rise in the use of prepectoral direct-to-implant (DTI) breast reconstruction, concerns remain regarding the potentially risk of complications, resulting in the selective application of the technique; however, the selection process was empirically based on the operator's decision. Using patient and operation-related factors, this study aimed to develop a nomogram for predicting postoperative complications following prepectoral DTI reconstruction.
Methods: Between August 2019 and March 2023, immediate prepectoral DTI was performed for all patients deemed suitable for one-stage implant-based reconstruction.
Endocrinologic Dysfunctions and Neuropsychiatric Sequelae in Pediatric Patients With a History of Central Nervous System Infection (ENDLESS): A Prospective Monocentric Study.
Pediatr Infect Dis J
December 2024
From the Department of Woman and Child Health and Public Health, Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy.
Introduction: Central nervous system (CNS) infections represent some of the most critical pediatric health challenges, characterized by high mortality rates and a notable risk of long-term complications. Despite their significance, standardized guidelines for endocrinological follow-up of CNS infection survivors are lacking, leading to reliance on the expertise of individual centers and clinicians.
Materials And Methods: Prospective monocentric observational study conducted at the Fondazione Policlinico Universitario Agostino Gemelli in Rome, Italy.
Effects of body weight-supported Tai Chi Yunshou training on upper limb motor function in stroke patients: A three-arm parallel randomized controlled trial.
PLoS One
January 2025
Department of Rehabilitation, Seventh People's Hospital of Shanghai University of Traditional Chinese Medicine, Shanghai, China.
Objectives: To form a unique body weight support-Tai Chi Yunshou (BWS-TCY) training method, apply it to the treatment of upper limb dysfunction after stroke, and provide a new safe and effective treatment method for the clinic.
Methods: A total of 93 subjects were recruited and randomly divided into conventional rehabilitation treatment (CRT) group, BWS-TCY group and traditional robot-assisted training (RAT) group in equal proportions. Subjects in the CRT group received 60 minutes of CRT daily.
Risk-Based Screening of Atrial Fibrillation in General Practice (R-BEAT): A randomised Cross-over Trial.

January 2025
HRB Clinical Research Facility Galway, School of Medicine, University of Galway, Galway, Ireland.
Background: The optimal approach to the diagnosis of atrial fibrillation in primary care is unclear.
Aim: To determine if external loop recorder (ELR) screening improves atrial fibrillation detection in community dwelling adults with a CHA2DS2-VASc score of greater than two.
Design: Randomised cross-over clinical trial.
Risk prediction for elderly cognitive impairment by radiomic and morphological quantification analysis based on a cerebral MRA imaging cohort.
Eur Radiol

Institute of PLA Geriatric Medicine, The Second Medical Center & National Clinical Research Center for Geriatric Diseases, Chinese PLA General Hospital, Beijing, China.
Objective: To establish morphological and radiomic models for early prediction of cognitive impairment associated with cerebrovascular disease (CI-CVD) in an elderly cohort based on cerebral magnetic resonance angiography (MRA).
Methods: One-hundred four patients with CI-CVD and 107 control subjects were retrospectively recruited from the 14-year elderly MRA cohort, and 63 subjects were enrolled for external validation. Automated quantitative analysis was applied to analyse the morphological features, including the stenosis score, length, relative length, twisted angle, and maximum deviation of cerebral arteries.
